<div class="card">
[WARNING ->]<template ngFor let-panel [ngForOf]="panels">
<div role="tab" id="{{panel.id}}-header" [attr.ar"): ng:///home/ashish/workspace/angular/node_modules/@ng-bootstrap/ng-bootstrap/accordion/accordion.d.ts.NgbAccordion.html@2:4

Duplicate of #1337 (check #1337 (comment)) that will be solved via #1439. For now you can safely ignore the warning - we are perfectly aware of it and will remove it as soon as we drop 2.x support via #1439.
